Edsall coached guard Donald Thomas, and cornerbacks Darius Butler and Robert McClain during his tenure at UConn. And since he’s been at Maryland, defensive tackles A.J. Francis and Joe Vellano, as well as receiver Kevin Dorsey have also been rostered by the New England Patriots.

Perhaps there will be more to add to that list. The Patriots head coach, an Annapolis High graduate, was spotted at Byrd Stadium in College Park for the Terps pro day Thursday.

Patriots director of player personnel Nick Caserio was also in attendance, reportedly serving as quarterback for the workouts.

Maryland’s 2015 class of NFL draft prospects includes wideouts Stefon Diggs and Deon Long – coached by former NFL receiver Keenan McCardell, who played for Belichick during his tenure with the Cleveland Browns – and also defensive lineman Darius Kilgo and Andre Monroe.

The 6-foot, 195-pound receiver caught 150 passes for 2,227 yards and 14 touchdowns over three seasons with the Terrapins. And in addition, he rushed for 187 yards on 32 attempts, and tacked on 1,472 yards and two touchdowns as a kick returner. Projected as a fifth- or sixth-round pick this spring, Diggs ran a 4.46 40-yard dash, a 7.03 three-cone and a 4.32 short-shuttle at the NFL Scouting Combine in February.

Long was also invited to Indianapolis, where the 6-foot, 192-pound target recorded a 4.51 40-yard dash, a 6.98 three-cone and a 4.27 20-yard shuttle in timed drills. A well-traveled receiver who’s been part of three Division I programs and a junior college, Long caught 51 passes for 575 yards and two touchdowns for Maryland last season. He is seen as a possible seventh-rounder or priority free agent.

Kilgo and Monroe are as well.

The 6-foot-3, 319-pound Kilgo met with the Patriots on Wednesday, according to Aaron Wilson of The Baltimore Sun, after being three-year starter for the Terrapins at nose. And the 5-foot-11, 282-pound Monroe finished his Maryland career as the school’s all-time leader with 25 sacks, after amassing 10.5 as a redshirt senior last season.
